# How to swap into a swap pool that is depleted
Check pool liabilities and reserves on the [swap pools](https://app.nabla.fi/swap-pools) page.
## Pool Liabilities
\
Liabilities describe the amount of assets deposited by the LPs. The pool is liable since LPs are entitled to withdraw their assets any time.
## Pool Reserves
\
Reserves describe the amount of assets in the pool at a given time.
## Balancing Pools
\
For example, if the USDC pool has 1M liabilities but 800k reserves, this means you need to "swap into" the USDC pool to balance it. \
\
You should [swap](https://app.nabla.fi/swap) USDC for any other asset. By swapping, you add USDC to the USDC pool reserve, while subtracting from the pool reserve of the asset you swap for.
\
LPing does not change the depletion because if you add more as an LP, the liabilities increase as the pool needs to pay back more tokens.
